Yep, still interested. And I still want to know, if possible, the answer to the question I asked in my initial post :).

Also, as I would assume our characters retain all magical knowledge they had as professors, BUT magical power also increases with age so I would assume we don't have access to everything in our regressed state, what are some limitations that our characters have? (For reference, the character I'm thinking of, before the regression, was proficient in obliviation, legilimency, occlumency, and mind magic in general up to and including Imperio)
